Abstract

Currently, there are no markers to predict response to acute myeloid leukemia (AML) therapy and patients have to wait for a period of 3-6 months to see treatment response. The study aimed to analyze changes in protein expression in AML cells between different categorization risk groups using proteomics techniques. Six peripheral blood (PB) and six bone marrow (BM) samples at diagnosis and remission times were collected from AML patients. Another Six PB samples were collected from different categories of AML. All samples were analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS). The levels of proteins in patients with AML were compared at different categorization risk, individual response to treatment and clinical characteristics. Twenty-one and 145 differentially expressed proteins were identified with disease progression and risk categories of AML, respectively. Three (3) proteins were noticeably highly expressed out of the range of others proteins by at least 3- fold difference between diagnosis and remission. Two other of proteins were up regulated by more than 10 folds between risk categories of AML. Furthermore, 4 proteins were found to be expressed in one risk category, but were not detectable in other two risk categories. The study showed that a panel of differentially expressed protein profiles might serve as more objective biomarkers for accurate stratification of different risk categories of AML.

Özet

Günümüzde, akut miyeloid lösemide (AML) tedavi yanıtını belirleyen marker yoktur. Hastalar, tedavi yanıtını görebilmek için 3-6 ay kadar beklemeleri gerekmektedir. Bu çalışmada farklı risk gruplarında AML hücrelerinin protein ekspresyon değişiklikleri, proteomiks tekniği ile çalışılmıştır. Altı AML hastasının tanı anında ve remisyonda alınan periferik kan (PK) ve kemik iliği (Kİ) örnekleri analiz edilmiştir. Diğer risk kategorisinden 6 AML hastasının PK analiz edildi. Örneklerin hepsi liquid chromatography tandem mass spectrometry (LC-MS/MS)’de analiz edildi. Hastaların protein ekspresyonları, farklı risk kategorisine, tedavi yanıtına ve klinik özelliklerine göre analiz edildi. Hastalık tedavi yanıtlarına göre 21, risk gruplarına göre bakıldığında ise 145 farklı protein ekspresyonun olduğu saptandı. Üç proteinin tanı anında ve remsiyonda normal aralıkların çok üzerinde; en az üç kat yüksek olarak eksprese olduğu saptandı. Farklı iki proteinin ise farklı risk gruplarında en az 10 kat faarklı olarak eksprese olduğu görüldü. Ayrıca, 4 protein bir risk grubunda eksprese olur ikeni, diğer iki risk grubunda ekspresyonu saptanacak düzeylerde değildi. Bu çalışma farklı protein ekspresyon panlellerinin, farklı risk sınıflamalarında daha objektif biyomarker olarak kullanılabileceğini göstermiştir.
